The HEXACO Personality Inventory (HEXACO-PI) operationalizes the six factors obtained from lexical studies of personality structure in several languages. In this study, psychometric properties of the HEXACO-PI were assessed using a community adult sample and also using observer reports, thereby extending the previous investigation relying only on self-reports from a college student sample. In addition to examining the original 24 HEXACO-PI facet scales, the authors also examined two new facet scales—Altruism versus Antagonism and Negative Self-Evaluation—that assess constructs located interstitially among the factors of the HEXACO space. The HEXACO-PI again showed favorable psychometric properties in terms of reliability and factor structure and also showed high levels of self/observer agreement.
